General
The new Blue Mars release is now much smaller, at around 320MB compared with the previous download size of 1.3GB. This is mainly due to no longer bundling Cities in the download. See the City Browser section below for further details.

City Browser
The new City Browser lists all cities that you currently have on your HD and lists all the other cities available on the AR servers. Selecting a city in the browser will now download it in the background. The time to download will depend on your broadband speed. City file sizes will typically be in the 200MB - 500MB range. You must restart Blue Mars to be able to visit any City you have downloaded.
New Cities
The new Blue Mars release comes with two new Cities to explore, an update to an existing City, and a new bowling game.

Caledonia
Desmond Shang, well known in Second Life with his Caledon Victoriana sim, has established a colony now on Blue Mars, and named it Caledonia.

If Victorian Caledonia isn't quite your cup of tea, check out Pavonis, a tropical archipelago under the same management but with large islands available for development, not subject to Caledonia's 19th century thematic restrictions.

• Improved Communications Panel
• Purchased items go into Inventory

Introduction
With 2009 rapidly coming to a close, we have seen a number of changes in open-source Virtual World platforms and engines, with the noticeable departure of M.U.P.P.E.T., the arrival of Unity, and the no-show of Myst Online. This is the year-end round-up of the current state of play.

Changes through 2009
Visitors to the M.U.P.P.P.E.T home page are informed that the website is down for maintenance, as they get ready for the next version. However, that message has been there since at least August 2008, and neither of the two links on the home page, to the latest version of the software, and to the SIGGRAPH documentation, currently work. I think we can safely say that after more than a one year absence it is unlikely that they will return.

The big news during 2009 was the introduction of the Unreal Development Kit (UDK) from Epic Games, although it is still to be determined if this free games engine can be utilised to support Virtual Worlds. For this reason it is not included in this current list, but it has been the subject of separate articles in this blog. Also during 2009 came the announcement that the Unity multiplatform game development tool, was to be made available for free. Unity does appear to have all the ingredients necessary to support the building of Virtual Worlds, so I have included it in the current list.

Missing from the list is Myst Online, who made the following announcement more than a year ago:

Cyan Worlds, Inc. has agreed to put the program code sources for Myst Online: Uru Live into open source. The code sources that will be included are the code for the client, all the servers and tools. With the source to the client and the servers, fans should be able to set up and run Myst Online: Uru Live and bring Uru community back online.

However, there is still no sign of this being followed through.

Current Platforms

Croquet
The Croquet Project is an international effort to promote the continued development of the Croquet open source software development kit, for creating and delivering deeply collaborative multi-user online applications. Implemented in Squeak Smalltalk, Croquet supports communication, collaboration, resource sharing, and synchronous computation among multiple users. Applications created with the Croquet Software Developer's Kit (SDK) can be used to support highly scalable collaborative data visualization, virtual learning and problem solving environments, 3D wikis, online gaming environments (MMORPGs), and privately maintained/interconnected multiuser virtual environments. Since release of the Croquet SDK in 2007, the SDK has not been under active development. All continued development of the technology has taken place under the very active Open Cobalt effort.



Croquet is MIT licensed.

The Metaverse Project
The Open Source Metaverse Project, or OSMP, was a multi-participant shared virtual world online platform. This platform was free and open source software co-founded in 2004 by Hugh Perkins and Jorge Lima.

OSMP is loosely modeled on the World Wide Web borrowing ideas from existing worlds such as Second Life, Active Worlds, and There. This project aimed to produce an open source engine for the creation of streamed 3D worlds, also making it possible to interconnect existing worlds into a single open, standards-based Metaverse.

As of 2008, the project was no longer active. Most developers shifted focus to development of open source software compatible with Second Life, but the software is still available on SourceForge.
http://metaverse.sourceforge.net/

Ogre

OGRE (Object-Oriented Graphics Rendering Engine) is a scene-oriented, flexible 3D rendering engine (as opposed to a game engine) written in C++ designed to make it easier and intuitive for developers to produce applications utilising hardware-accelerated 3D graphics. The class library abstracts the details of using the underlying system libraries like Direct3D and OpenGL and provides an interface based on world objects and other high level classes.

OGRE has a very active community, and was Sourceforge.net's project of the month in March 2005.[2] It has been used in some commercial games such as Ankh and Torchlight.
http://www.ogre3d.org/

Open Cobalt
Open Cobalt is a free and open source virtual world browser and construction toolkit application for accessing, creating, publishing, and hyperlinking avatar-based multi-user virtual worlds that are accessible both on local area networks or across the Internet. It is designed to enable the deployment of secure virtual world spaces that support education, research, and the activities of virtual organizations. The Open Cobalt application is a type of 3D browser that can be used to define and access a network of interlinked 3D virtual environments in much the same way that web browsers are used to define and access web based content on web pages.

Opensimulator
OpenSimulator is a 3D Application Server. It can be used to create a virtual environment (or world) which can be accessed through a variety of clients, on multiple protocols. OpenSimulator allows you to develop your environment using the technologies you feel work best - we've designed the software to be easily extendable through loadable modules to build completely custom configurations. OpenSimulator is released under a BSD License, making it both open source, and commercially friendly to embed in products.

Project Darkstar

Project Darkstar is an open source MMOG middleware solution written in Java by the Project Darkstar team at Sun Microsystems. It is a research project currently headed by Sun Microsystems engineer Jim Waldo that was publicly released on August 30, 2007[1], and "aims to help developers and operators avoid a range of serious, yet typical, problems associated with massive scale online games, virtual worlds, and social networking applications today, including zone overloading, data corruption, and server underutilization."
http://projectdarkstar.com/

Project Wonderland

Project Wonderland is a 100% Java and open source toolkit for creating collaborative 3D virtual worlds. Within those worlds, users can communicate with high-fidelity, immersive audio, share live desktop applications and documents and conduct real business. Wonderland is completely extensible; developers and graphic artists can extend its functionality to create entire new worlds and new features in existing worlds.
https://lg3d-wonderland.dev.java.net/
https://wonderland.dev.java.net/index.html

Sirikata
Sirikata is an BSD licensed open source platform for games and virtual worlds. They aim to provide a set of libraries and protocols which can be used to deploy a virtual world, as well as fully featured sample implementations of services for hosting and deploying these worlds.

Unity

Unity is a multiplatform game development tool, designed from the start to ease creation. A fully integrated professional application, Unity just happens to contain the most powerful engine this side of a million dollars, but now available for free!
http://unity3d.com/unity/

VastPark

VastPark is virtual worlds technology done right. The framework is simple, distributed and extensible. It's not a single virtual world. Instead, it provides free software tools, APIs and open source libraries so you can deploy (and even monetize) your own virtual worlds and add ons for all kinds of organizations and purposes.
http://www.vastpark.com/

vr juggler

The VR Juggler project was started in 1997 by Dr. Carolina Cruz-Neira and a team of students at Iowa State University's Virtual Reality Applications Center. This ongoing work has produced a freely available open source, community-oriented virtual reality application development framework. VR Juggler is released under the GNU LGPL and will always be available for anyone and everyone to use free of charge.

As I mentioned in my Diary entry for the 13th November I have been involved with a small team of seven developers to establish whether the Unreal Development Kit (UDK) can be successfully used as a platform for creating standalone virtual worlds as opposed to just game modding.

With this purpose in mind, we started off by defining what users would normally expect from a Virtual World, then we investigated those definitions to see if the UDK supported them or not, then formulated tests to demonstrate compliance.

The definitions we used were that a Virtual World should be a virtual space, that is persistent, and where its residents can:

• Change their environment, either with inworld or offworld building tools
• Change their appearance, in terms of shape, skin, hair and clothing
  
• Teleport from one area, or one zone, to another
• Communicate with Chat, IMs, VoIP, Friending and Friends List
• Fly, run, walk, jump in a smooth and intuitive manner
• Have an economy, where virtual goods may be bought, sold and traded

I believe those are the 'core' functions of any virtual world that hopes to be successful, and it is these core functions that need to verified and validated to determine if the UDK can indeed be used to create Virtual Worlds.

Each of the developers took on an area from the above list to investigate, and the initial results are now in.

Building Tools
The UDK has no provision for inworld building (like SL), and objects are built offworld in 3d apps then uploaded. We are currently looking at a hybrid approach where there will be a low-def building toolbox within the world, using primitives similar to SL, but with the prim set extended, and with the ability to import far more detailed meshes from external 3d apps. We are encouraged by the amazing work of Gary's Mod.

Avatar Appearance
I don't think I have seen anything better than the one in APB, a game built on the Unreal Engine. It just shows what is possible with this awesome engine.




















Teleporting
We now know that a teleport system is available in the UDK, as a good example of this is in the "DM-Deck" map, where you can teleport from a low ground position to a high platform.


We will start looking at maintaining avatar appearance and inventory across teleports next.

Communications and Friending
Only basic console chat is available in the UDK. In UT3 and other Unreal games, VoIP, chat, IMs, Friending etc, was achieved by their tie-up with GameSpy, which became an integrated partner. Alternatives to GameSpy, such as Raptr, and Xfire are being investigated, but also possibly an in-house solution. At the very least, Skype could be used.

Movement
Walking, running and jumping are all included in the UDK, and the controls are what users of games expect. There is no native support for flying (as in SL) so this will need to be coded.

Economy
There is no provision in the UDK for an inworld economy, so offworld economy models are currently being researched (similar to XStreetSL). Inworld, money can be treated as just another inventory item, and be earned, paid, spent etc as normal. If the 'rezzing' of objects inworld can be solved, then inworld stores would be feasible.

Below is the text of the post I made to the OpenSim core-devs about my decision to leave the OpenSim project.

I have decided to leave the Opensim project. You will probably not even notice if I leave, as not being a programmer my only inputs were the writing of the step-by-step tutorials, the drafts of the OpenSim User Manual on the Forge, and helping out in the IRC channels, for newcomers. You may find my reasons for leaving Opensim interesting though (and please do not construe any of my reasons as an attack on anyone).

1. The Platform
I raised this several times in the past in IRC, and made posts on my blog about the product lifecycle of the platform. I believe that the platforms underpinning both Second Life and Opensim are quite long in the tooth now, and I questioned how much product lifecycle there was left, particularly given that Opensim is now nearing 3 years of development, is still in Alpha, and if the current release of 0.6.7 is any indicator, then still only around two thirds into the development cycle. With the (inevitable) coming of much superior platforms, such as Blue Mars (as a virtual world); and Unity, for browser-based Virtual Worlds; and now UDK (for creating sandboxes, standalones, and open grids), then I fear that Opensim has missed the boat as far as the remaining lifecycle of the platform is concerned. When you show people what is possible with these engines (for example this avatar editor for the forthcoming APB (using the Unreal Engine):  or this city  (using the CryEngine), then neither SL nor Opensim stands comparison.

2. Lack of Support for Currency in Opensim
I felt the impact of this when I first made the switch from SL to Opensim. I had a thriving RP sim in SL (over 50 people, mainly female) and they all agreed to follow me over to my Opensim and the OSGrid. However, within a month they had all left, citing the same reasons, the lack of places to shop to buy the quality stuff they wanted (skins, hair, clothes etc), as a quality appearance, and the fun of shopping is what all the females placed high on their requirements from a Virtual World. They drifted back to Second Life, and the guys followed them. I have always believed that the lack of support for currency in the core was a mistake, but that is just my opinion.

3. Marketing
I have also raised this issue several times, and blogged about it. It is far from clear just who an eventually released Opensim is actually aimed at. I think that any company that is interested in a firewalled corporate solution to collaboration and prototyping will already be looking at the Enterprise solution that is currently available from Second Life; that any indie group that is thinking of running a themed grid will need an economy to stay viable; and any individual who is looking for a private sandbox solution for their SL work will need full compatibility (which is not the case with the OS version of LSL diverging from the SL LSL). So, just who is the platform aimed at? I was also very disappointed in the view of one of the core devs who said that 'marketing is a null concept for us'.


I am currently designing and creating cities for Blue Mars, and involved in a team for proving the UDK as a platform for the design and creation of sandboxed or standalone Virtual Worlds (as opposed to purely games), and with so much documentation available for these mature engines (particularly for the UDK, Blue Mars lags behind somewhat in that department, but are working to put that right), I am achieving the productivity I want, building the worlds that I want, with stable crash-free platforms.

However, I do wish the Opensim team the very best in their endeavours, and I sincerely hope their goals are eventually achieved.

If anyone would like to take over the main Opensim Tutorials pages and the Additional Tutorials (they will need some updating following several changes) then I am more than willing to pass the posts over, and of course the Opensim User Manual is there in the Forge for anyone to develop further.

Best Regards and Good Luck

Blue Mars Progress Painfully Slow
I have been stalled in my city creation for weeks now. This has been mainly due to a lack of information on scripting, vehicle editing, and understanding the differences between the editors. I see in the Developer Forum poor Takuan has been soldiering on, with little or no support, in trying to get to grips with Lua scripting. He must be very frustrated.

I hope more resources become available soon so I can resume my build.

UDK Development Making Good Progress
I have been working on a proof-of-concept virtual world development using the Unreal Development Kit I blogged about earlier. With another developer from Blue Mars and a modder named Ridders from the UDK forum, we have been conducting experiments to establish a net-wide interface to enable a server running a map or game to be accessed remotely by another client across the net. I am happy to report that these experiments have been successful, and remote connections are now possible, and understood. The need for experimentation is also due to the lack of good quality step-by-step documentation, but in general the wealth of documentation available to UDK modders is huge, compared to the documentation available for Blue Mars.

Here are some of the resources I have been using:

Yesterday, November 4th, 11:15 am - 12:00 pm PST, Doug Thompson (Dusan Writer in Second Life) moderated a mixed-reality panel at Enterprise 2.0 in San Francisco and Metanomics inworld with:

• Mark Kingdon, Linden Lab's CEO, 
• Neil Katz, IBM Distinguished Engineer and Director IBM Virtual Spaces, CIO Office Innovation Initiatives, 
• Steve Aguiar, Program Manager at the Naval Undersea Warfare Center's (NUWC's) Metaverse Strategic Initiative,
• Douglas Maxwell, Program Technology Lead also at NUWC's Metaverse Strategic Initiative.

Mark Kingdon, CEO of Linden Lab, unveiled “Nebraska”, the LL code-name for a stand-alone solution based on the technology that runs the popular Second Life virtual world. “Nebraska” is the much-anticipated behind-the-firewall solution which allows enterprises to host their own virtual world environments within their organizations, which was first introduced back in April.

Mark spoke about the benefits of the platform, the intended audience, and how it fits into the broader challenges and opportunities of “enterprise 2.0”. Mark was joined by a number of customers who had used Nebraska during the closed beta phase of development.

Nebraska consists of two rack-mounted servers, hosting two software packages: a world server and a voice server, which can be installed on an enterprise's network, and as it does not have to stream all the content that LL normally streams for Second Life, it is blazingly fast. Similar to the standalone version of Opensim, but much more polished.

The avatars in Nebraska are all 'suits', with none of the Pamela Anderson and Professional Wrestling lookalikes that seem to predominently populate Second Life. The package supports up to 800 avatars over 8 regions, each of which can be turned off, and replaced with another using a different theme. So, you could have training regions one week, then replace the regions with conference and show regions the next, saving to, and loading from, the region inventory at will.

But how much does all this cost? Well, the mooted price is US$55,000, plus US$14,000/year in fees, which should bring a big sigh of  relief to the open-source Opensim community.

Nebraska is aimed at providing enterprises with a SL-looking virtual space for their corporate activities, without the seedy association of SL itself.

In addition to Nebraska, Mark also introduced the Work Marketplace, where corporate customers could download ready-made regions, providing solutions for virtual conferences, events, exhibitions, training, marketing, etc., and a selection of business and work-related avatars, office suites, and much more, for their Nebraska customers, under a site license.

It remains to be seen whether this is a major new direction for Linden Labs.

Unity
Early in 2009 I mentioned the recent trend in Virtual World design that required little or no downloads, and where all content was streamed directly to your browser (basically, if you can watch streamed movies on your PC you can use streamed games and virtual worlds). As we approach the end of 2009 one company stands out as the leader of this trend, Unity Technologies.



The Unity software allows anyone, with no programming experience whatsoever, to quickly develop games and virtual worlds, that can be run in a browser, using simple drag and drop tools. A player can start a game or visit a world on their home PC, then continue on the move via their mobile phone!

Up until recently, the Unity software came in two main flavours: Unity Pro, at US$1,499 and a cut-down version, Unity Indie, at US$200. That has now changed. Unity Indie has now been renamed to simply 'Unity' and is now available at zero cost, while still allowing the user to create commercial applications. The main restriction between Unity and Unity Pro is that Unity is limited to a maximum of 20 avatars per 'world', which is ample for most applications. Unity is available in both Windows and Mac versions, and versions are also available for creating applications for both the iPhone and the Wii.

The Unity download comes complete with a simple but powerful Editor, and a sample project, Tropical Paradise, which is available to browse, along with other projects in Live Demo format on the Unity website.



Models and objects for your world can be created in almost all current 3d applications. A list of 3d formats, image formats, video and audio formats supported is available on the Unity Asset Importing page.

Of course, once you have created a virtual world you will need to host it so your customers/friends can access it through their browsers. Hosting can be on a dedicated server, a Virtual Private Server, or even on your home PC if your upload speed is fast enough. So, what do you do if your ISP does not quote your upload speed? The answer is - you measure it. Use one of the internet connection speed measurement services. The one I like best is SpeedTest.NET Just select the recommended server to test with (click on the yellow pyramid), and it will measure first your download speed, then your upload speed. My upload speed is 1Mb/sec and it handled myself and a visiting friend with no problem at all. I did not check how many avatars 1Mb/sec could handle (but hey, you have to have something to check yourself, right?).

FriendsHangout
Many Games, 3d Chat Rooms and Virtual Worlds have been built now using Unity, and  one such company that provides over 4000 chatrooms, virtual worlds, and custom 3D worlds, using Unity, is FriendsHangout (terrible, unimaginative name, I know). You select the World you wish to visit from a rotating set of destinations boards (think Blue Mars Destination Island here, but rotating).


You can also create your own custom chat room and virtual world and buy furniture and various props to add your own design to each and every item in their catalogue.

While the most visible faces of the Avatar-Reality team have been working on the Blue Mars Client, providing more and more functionality, squashing bugs, arranging Meet & Greets, gathering feedback etc, other teams have been busy creating the developer tools, and providing detailed manuals for their use on the Blue Mars wiki pages.

The Wiki team is led by Scott Matsuda, the CSR, QA, and QC Manager at Avatar Reality Inc.

The Getting Started section of the Developer Guidebook explains the different types of developer in Blue Mars:

The Item Editor
Made specifically to have everything an Item Creator needs

Sandbox Item Editor is a 3D geometry model viewer and material editor for Blue Mars Project. The primary purpose of this tool is to convert 3D models in Collada format into a Blue Mars internal data format, examine the results visually and edit material properties of converted models as desired. Sandbox Item Editor uses CryENGINE2 for rendering; thus, it displays objects exactly as they will appear in the game. The manual provides a detailed description of its menu commands and special functions.

Note: in some images and documents, linked to this page, the Item Editor is also called Sandbox Viewer, which is the old name of this tool.

The new Blue Mars client has a few more tricks up its sleeve.

The login screen now has buttons to link to the Tutorials pages, and for retrieving a lost password.
